The
Clearstream System is one of the finest aerobic wastewater systems available
today. Our system converts the sewage from your residence or business into a
clear, odourless liquid. This high degree of treatment is accomplished at a
remarkable low operating cost per month. The system has been simplified over
the years to make it as inexpensive to operate and as low in long-term
maintenance as possible. Homeowners who have lived with the nuisance of a
septic odour lingering in their neighbourhood will truly appreciate the pleasure
of owning a Clearstream System. Clearstream Model N comply with NSF Standard 40
for Class 1 systems.

PROCESS DESCRIPTION

The Clearstream Wastewater
Treatment System operates in the extended aeration mode of the activated sludge
process.

Wastewater enters the aeration
chamber of the system through a 4" Sch. 40 PVC inlet pipe. The wastewater is
then mixed throughout the aeration chamber by releasing compressed air near the
bottom of the chamber through a fine bubble diffuser. The rising air bubbles
transfer oxygen to the wastewater which allows aerobic organisms to thrive and
ultimately decompose the incoming waste matter.

The turbulence caused by the rising
air bubbles also creates a mixing pattern, which keeps the sludge in
suspension. As incoming wastewater enters the aeration chamber, existing "mixed
liquor" from the aeration chamber is displaced into the bottom of the
cone-shaped clarifier.

The
clarifier chamber allows the water to still so that suspended solids in the
mixed liquor" can settle back into the aeration chamber for further biological
breakdown.

The remaining clear water in the
upper zone of the clarifier chamber is then discharged through the surge control
weir and out the 4" Sch. 40 outlet pipe.

When properly loaded and
maintained, the aforementioned process allows the Clearstream Wastewater
Treatment System to provide years of satisfactory service for the consumer.
Clearstream Model N meets the performance requirements of NSF Standard 40 Class
1 with a 30-day average of <25 mg/l CBOD and <30 mg/l TSS. Actual NSF test
results used to determine if Clearstream met Standard 40 requirements averaged 6
mg/l BOD and 9 mg/1 TSS.
